Sealing Ability of Different Root Canal Sealers - A Systematic Review
Objectives: The objective of this review was to evaluate the apical sealing ability of different root canal sealers ..The objective of root canal treatment is to clean and shape the root canal system, removing all organic material and to seal this system three dimensionally with a permanent filling. To achieve this, it is believed that the root canal filling must seal the pulpal space both apically and laterally to prevent further apical irritation from incomplete elimination of bacterial products and from communication between the periradicular tissues and the oral cavity . Root canal fillings frequently consist of a core material and sealer. It is the role of the sealer to ensure an effective apical seal
Methods: EXPERIMENTAL METHOD:
SOURCES
An electronic search was conducted of the PubMed, MEDLINE and MeSH data bases from 1979 to 20th July 2011. Hand searching included relevant journals and bibliographies of all relevant papers and review articles from 1993 to 2011.
STUDY SELECTION;
The title, keywords and abstracts of reports identified from electronic searching for evidence of following criteria were examined:
Studies done on human teeth,
Only apical leakage studies,
Studies using fluid filtration model,
Studies comparing the sealing ability of different rootcanal sealers such as epoxy resin based sealers, glass ionomer based sealers, calcium hydroxide based sealers, zinc oxide eugenol based sealers and methacrylate based sealers.
Results: Results showed that as a core material gutta percha showed better results and epoxy resin sealer showed better apical sealing ability than other sealers using fluid filtaration model
Conclusions: There are no clinical trials to draw a direct conclusion. Based on the current evidence available, epoxy resin sealer and silicone sealer offer the best apical seal. However clinical evaluations are required with large sample sizes, to identify any difference in the seal offered by these root filling material and thereby treatment outcomes.
